This is one of the AEC Critical Review Series. The author was with the Air Resources Atmospheric Turbulence and Diffusion Laboratory, Environmental Science Services Administration located in Oak Ridge, Tennessee. This review was prepared for the Nuclear Safety Information Center at the Oak Ridge National Laboratory. Gary Allen Briggs earned a Ph.D. in Meteorology at Penn State University. He worked as a research meteorologist for NOAA in Oak Ridge, TN, and for the EPA in the Research Triangle Park, North Carolina, furthering scientists' understanding of plume rise and dense-gas dispersion. He is best known for the highly influential "Briggs Equations" developed early in his career. Weather was always one of his passions. A classic work on the subject of air pollution plumes is that by Gary Briggs. In hydrodynamics, a plume is a column of one fluid moving through another. Several effects control the motion of the fluid, including momentum (inertia), diffusion and buoyancy (density differences). Pure jets and pure plumes define flows that are driven entirely by momentum and buoyancy effects, respectively. Flows between these two limits are usually described as forced plumes or buoyant jets. "Buoyancy is defined as being positive" when, in the absence of other forces or initial motion, the entering fluid would tend to rise. Situations where the density of the plume fluid is greater than its surroundings (i.e. in still conditions, its natural tendency would be to sink), but the flow has sufficient initial momentum to carry it some distance vertically, are described as being negatively buoyant. Condition: Good.
